RETOUCHING-MACHINE.

Application filed January 30, 1919. Serial No. 274,131.

To all whom t may concern: ,j

Be it known that I, OSCAR S. Talinn, a citizen of the United States of America, and a resident of the city of 4Bloomfield, county of Essex, `State of New Jersey, have invented and do hereby lay claim to certain new and useful Improvements in Retouchng-Machines, of which the following is a description and specification.

My invention relates to improvements in instruments used by photo-engravers and others for the purpose of retouching photographic negatives when it is desired to produce Aa tone simulating the texture, particularly of flesh or fabric. This result is accomplished by a combination of mechanical and electric or other contrivances cordinated to, and specifically arranged for the purpose intended.

The accompanying drawings will now be referred to to more fully describe the invention, of which:

Figure 1 is a longitudinal section of an instrument embodying the novel features of this invention.

Fig. 2 shows a portion of the instrument viewed at right angles to Fig. 1.

Figs. 3, t and 5 are transverse sectional views on line 3-3, 4 4 and 5-5, Fig. 1 respectively.

The cap 6, is securedto the main or central portion 7 of the casin by being screwed on the bearing 8 of the rive shaft, which bearing is by its screw thread securely held stationary in a counter screwthread in the top of the central portion 7 The casing is completed by a section in the form of a per forated plug or bushing 9, which is screwed into a recess formed inthe lower end of the central portion 7, and butts against the end of the bearing 10, of the pencil carrying shaft, said bearing having a flange v 11 formed to seat in the recess in the end of the central portion 7, and is thereby `held .in fixed axial position.

The drive shaft is composed of two parts 12, and 13, which are held in axial aline- `ment by the end of part 12 fitting in a socket-14, formed on the upper end of part 13, said socket benghformed with a slot into which fits a feather ory spline 15 on the part 12 whereby while the two parts of the shaft may be longitudinally .adjusted they will under all circumstances be relatively the axis of the shafts 13 and 28, when the bearing 2O is longitudinally shifted by the finger pieces 25. A rm and positive joint between the ends of the shafts 13 and 28 is provided by 'this hinge connection, insuring positiveness of action of the ends of the shaft 28, revolving around the axis of t-he instrument in varying circles, the diameters of which are determined by the angular settings of the link 36.

I claim:

1.. In a. retouching instrument, a drive shaft. a pencil carrying shaft and a universal bearing therefor in line co-axial with the drive shaft in combination with an adjustable connection positively joined to the adacent ends of the two shafts and means for setting the connection, whereby the end of the pencil carrying shaft may be set in different radial positions relatively to the axis of the drive shaft and revolved around said axis in unison with the rotation of the drive shaft.

2,.'In a retouching instrument, a `drive shaft, a pencil carrying shaft and a universal bearing therefor in line co-axial with the drive shaft in combination with an adjustable connection comprising a link and pivots on which its ends are free to rock and by which it is positively joined to the adjacent ends of the two shafts and means for setting the connection, whereby the end of the pencil carrying shaft may be set in different radial positions relatively to the 'axis of the drive shaft and revolved around said axis in unison with the rotation of the drive shaft.

3. In a retouching instrument, a drive shaft, a pencil carrying shaft and a universal bearing therefor in line co-axial with the drive shaft, said shafts having slots formed in their adjacent ends, in combination with a flat link with its ends fitted to work in the slots and pivotal pins or bolts passing through the sides of the slots and vthe flat link, and means for varying the disnected at its ends to the adjacent ends of the two shafts and means for varying the distance between the ends of said shafts longitiidinall3Y the axis and coineidently setting and holding the ends or" the pencil carrying shafts away frein the axis.

A retonchinp` instrument, comprising` a drive shalt, bearine's therefor, a pencil or stylus carrying shaft provided with a unirersal hearing mediate its ends haring a flange at one end and longitudinally sta tionary in line coaxial with the hearings of the drire shaft, a casing in which the hearings are held consisting` of a main central portion haring a screw threaded recess at tudinally the axis and eoincdently setting and holding the ends of the pencil carrying 25 shafts awa)T from the axis.
